Application filed April 4, 1921. Serial No. 458,188.

To ZZ whom t may concern.'

Be it known that I, JOHN IsELE, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented new and useful Improvements in a Mechanical Device, of which the following is a speciiication.

My invention relates to a mechanical device, and has for one of its objects the provision of a frame carrying a ily-wheel provided with a spring-actuated lever for carrying the wheel over a dead center.

lVith the foregoing and other objects and purposes in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein described can be made within the scope of what is claimed Without departing from the spirit of the invention.

In the accompanying drawings- Figure 1 is a side elevation of the flywheel, showing the arrangement thereon of the lever, spring and gears, constructed in accordance with my invention.

F ig. 2 is a sectional elevation on line 2 2, Fig. l.

Fig. 3 is a perspective view of the device mounted on its frame.

eferring to the throughout which like designate like parts` The numeral 1 designates a frame provided at its ends with cap members 2, which support bearings 3 rotatably supporting the ends of a shaft 4.

Intermediate the ends of the shaft 4 is rigidly secured a fly-wheel 5, the shaft also rotatably supporting a toothed gear 6.

7 is a pintle rigidly secured to the flywheel and rotatably supports a gear 8, which is provided upon its periphery with teeth meshing with the teeth on the gear 6, and has on one side a recess 9 in which is coniined a coil spring 10, which has one end rigidly secured to the pintle 7 and its opposite end secured to the gear 8 by means of a pin l1.

12 designates a drawings in detail, reference characters pintle projecting out from the same side of the ily-wheel as the pintle 7 and rotatably supports, intermediate its ends, a rocker 13, which has an intermediate arcuated portion 14 provided with teeth meshing with the teeth on the gear 6, and two oppositely disposed arms 15.

The oscillation of the rocker 13 upon the pintle 12 is restricted by pins 16, which project out from the side of the iiy-wheel and engage the arms 15 when the rocker is oscillated a proper distance in either direction.

The axes of the pintles 7 and 12 and shaft 4, are preferably disposed inthe same plane.

Upon the free end of the pintle 12 is rotatably mounted the lower end of a lever 17, which is provided at its upper end with a crescent-shaped cross-head 18.

Upon opposite sides of the lever 17 are rigidly secured the upper ends of springs 19, the lower ends of which are in movable engagement with the upper side of the arms 15, the arrangement being such as to allow of a certain movement, under spring tension, of the lever 17 relative to the rocker 13.

The relative sizes of the gears G and 8 and the arcuated portion lil, may be approximately as shown in the drawings, or they may be proportioned otherwise as best suited to the tension of the spring 10 and the operative resistance of the lever 17.

The wheel 5 may be operated in either direction by changing the tension ofthe spring 10 relative to the pintle 7 and gear 8, however, to assist in describing the construction of the device as well as' its modus opewmci it may be presumed that it is in its normal position when the axes of the pintles 7 and 12 and shaft 4, are disposed in the same vertical plane, and the longitudinal axes of the lever also in the same plane, and the spring 10 wound to rotate the `gear 8 in the direction indicated by the arrow a.

To operate my device, the spring 10 is coiled against the tension of itself to cause the gear 8 to rotate in the direction indicated by the arrow a, to rotate the gear 6 in the direction indicated by the arrow 7) causing the rocker 18 to operate in the direction indicated by the arrow c and the lever` to oscillate in the direction indicated by the arrow Z carrying the cross-head 18 over the dead-center and causing the fly-wheel 5 to rotate in the direction of the arrow c.

The function of the lever 17 and crosshead 18, is to prevent the wheel stopping or remaining stationary in its normal position after having been manually rotated in the pro er direction.

aving described my invention, I claim: 1. A mechanical device of the character described comprising, :i :trame7 :i shaft journaled on the frame, e` fly-Wheel rigidly mounted upon the shaft, e spring driven zljever carried by the fly-Wheel, and ageared connection between seid first named gear and the lever. I

2. A mechanical device 05E ther character described comprising, e fra-me, t sha-ft journeled on the frame, a ily-Wheel rigidly mounted upon the shaft, a gear journaled on weer carried by the fly-wheel, and directing` the shaft, the exis of said gear in elineinent with the axis o the flywheel, e spring pro pelled O'ear operating with said lirst named gear, a rocker and lever pivotztlly supported by the ly`-Wheel, and a connection between said first named gear and Said rocker and lever.

In testimony of the foregoing being my own, I have hereunto eliixed my signature this 28th dey of'F-ebruery, 1921. JOHN SELE.
